In November last year, Yahoorevealed plans to encrypt all information that moves between its data centers by the end of Q1 2014, and it has delivered. As of March 31, traffic between its data centers is fully encrypted, the company announced today.

This comes after Yahoo switched on default HTTPS for all users of its Yahoo Mail service in January this year. The company revealed today that in the last month, it has also enabled encryption of mail between its servers and other mail providers that support the SMTPTLS standard as well. What’s more, the Yahoo homepage and all search queries that run there, as well as “most” Yahoo sites, also have default HTTPS now.

In the meantime, an encrypted version of Yahoo Messenger will land in the “coming months,” the company says.

“Our goal is to encrypt our entire platform for all users at all time, by default,” Alex Stamos, Yahoo’s chief information security officer, says. The company’s moves to increasingly protect user data come in the wake of NSA spying revelations.
